like I said, at every second the speed (30m/s) increases by 2m/s
so, 30m/s+ (2m/s^2)(4s)
so, 30m/s+ (2m/s^2)(4s)

how did you get that answer?
I mean like what is the formula to find out how far it was accelerating?

opps, I read the problem incorrectly. Here's the formula.
The distance = (1/2)*(acceleration)*(time)^2 + (initial velocity)*(time).
The distance = (1/2)*(acceleration)*(time)^2 + (initial velocity)*(time).

what is the initial velocity?

30m/s (the speed you start with)

but i got 184 for the distance...is that right? And also, on this answer sheet it says that the distance is 136 not 184. Is that correct or wrong?
